Demolator

Following the Thousand year war with the Alien Demolators, the last remnants of the human race are being transported across the galaxy in cryogenic suspension aboard the B.S. Quinn (Battle Star). The Demolators however have invaded the cargo bay and it is your job to destroy the Demolators and to protect the human cargo.

All you have to defend mankind with is Xeno (popularly named "the Phobe") the ultimate Robot. You can control his movements on two planes and fire an ultrasonic Cannon to defend the last remnant of humanity with.

Characters

1. Demolator (100 points)
   They seek to demolish your cargo. Their numbers increase from four in the first attack wave, up to nine in attack wave six. Wave seven sees their number decreased to four again and this sequence starts to repeat itself. On wave one, every seventh cargo crate a Demolator passes under is affected. This decreases to every sixth on wave two, down to every cargo crate on wave seven. Wave eight sees their demolition rate decreased to damaging one in every seventh cargo crate again.
2. Minor (200 points)
   This character appears at a random position on the screen; if it lands on a crate, the crate is destroyed. The Minor sits in the same position for a time, after which it mutates into a deadly mine which cannot be destroyed. As attack waves increase, the frequency of the Minor's appearance increases and the time it takes to mutate decreases. This also happens if the player takes too long to destroy the last four Demolators in an attack wave, the idea being to force the player to get on to the next attack wave.
3. Protector (500 points)
   This character fires bullets at you. The fire rate increases with the number of attack waves. The Protector first makes an appearance in the second attack wave and their numbers increase up to a total of six in attack wave seven.
4. Trackor (300 points)
   This character first makes an appearance in wave three. It actually homes in on your position when both of you are in view on the screen. The maximum number of Trackors is reached in attack wave six, when there are four of them. Now in wave eight this number is reduced to one, but the ability to fire bullets is obtained. On wave fourteen, the number of Trackors is reduced to one again and the ability to fire bullets is lost. However, the Trackor now becomes indestructable. Attack wave twenty sees the ability to fire bullets return. Hence the game reaches its most difficult stage on attack wave twenty-four.
